Abstract
The invention discloses a method for preparing colored toner used for laser printing and electrostatic copying. The invention combines with bulk polymerization, phase inversion polymerization, suspension polymerization technology and emulsion polymerization technology, and comprises the following steps: firstly, colorant and other additives are mixed with trace macromolecule, monomer and initiator completely for bulk polymerization for several hours, and aqueous phase solution which is dissolved with surfactant and dispersant is added to carry out the phase inversion and then polymerization is continuously carried out to obtain the product. The method obtains red, yellow and blue tricolor toner by polyreaction directly; the method has simple technology, less investment on equipment, energy saving and the uniform coloring of the product; and resin molecular weight shows bimodal distribution, thereby being good for fixation performance. The method overcomes the problem that unimodal distribution of the resin molecular weight causes poor fixation effect, uneasy even distribution of the colorant in the colored toner and over-wide particle size distribution during preparing the colored toner by the polymerization process.
